Those who live comfy, what do you do?

I do not want to do school for longer than I have to, but I obviously want financial stability. I thought about an OB ultrasound tech, but certain factors are weighing me down. So, those who didn’t spend forever in school but live comfortably, what do you do currently? If you only have one source of income I would love to hear from you as that’s how I see my future.
